An antenna apparatus and an electronic device are provided. The electronic device includes a plurality of metal parts, an antenna radiator arranged around the plurality of metal parts, and at least one sub antenna radiator arranged to electrically connect with the antenna radiator around the antenna radiator, and prevent deterioration of radiation efficiency of the antenna radiator caused by the plurality of metal parts.

Antenna apparatus and electronic device having the same

An electronic device for communicating in a network is provided. The electronic device includes a circuit board, a frame, a feeding structure formed on the circuit board, and an antenna unit disposed in a plane at a predetermined angle with respect to a surface of the circuit board. In addition, the antenna unit is disposed apart from the frame in electrical connection with the feeding structure.

Electronic device

In one embodiments, an electronic device including an antenna with a ring-type structure is disclosed. The electronic device includes a metal bracket and the antenna. The antenna includes a first metal ring surrounding the metal bracket, where the first metal ring has at least two sections separated by at least one gap. At least one section may operate as a radiator through radio frequency (RF) feeding at least at one portion thereof. A second metal ring may be electrically connected, at least at one point thereof, to a ground of the electronic device or to the first metal ring. At least one section of the first metal ring may operate as a monopole antenna, as a PIFA antenna, or as a loop antenna, via suitable feeding.

Electronic device with antenna having ring-type structure

An electronic device including a processor and an antenna device is provided. The antenna device includes a power feeding unit, a first radiation section connected to the power feeding unit, and a switching element including a first terminal electrically connected to first portion of the first radiation section, and a second terminal electrically connected to a second portion of the first radiation section. The processor uses a first resonance frequency band when the switching element is opened and uses a second resonance frequency which is different from the first when the switching element is closed.

Electronic device and method of operating the same

A portable terminal includes an antenna device having a circuit board on a surface of which a conductive layer is formed, a slit that removes a portion of the conductive layer and extends in a direction, an auxiliary board positioned on the slit to face a surface of the circuit board, and a radiation pattern formed on the auxiliary board, in which the radiation pattern is disposed to partially enclose the slit. Even when the radiation pattern is disposed on the conductive layer, induced current generated around the slit can be controlled in the same direction as signal power, thereby preventing radiation performance from being degraded by an inverse current phenomenon in spite of disposition of the radiation pattern on the conductive layer.

Antenna device for portable terminal

In one embodiment, an electronic device including an antenna with a ring-type structure is disclosed. The electronic device includes a metal bracket and the antenna. The antenna includes a first metal ring surrounding the metal bracket, where the first metal ring has at least two sections separated by at least one gap. At least one section may operate as a radiator through radio frequency (RF) feeding at least at one portion thereof. A second metal ring may be electrically connected, at least at one point thereof, to a ground of the electronic device or to the first metal ring. At least one section of the first metal ring may operate as a monopole antenna, as a PIFA antenna, or as a loop antenna, via suitable feeding.

Disclosed is an antenna device for a portable terminal, including a circuit board having a conductive layer attached on a surface, a first slit formed by partially removing the conductive layer in a position adjacent to one side of the circuit board, the first slit extending in parallel with a lateral periphery of the circuit board, a radiation portion comprising part of the conductive layer positioned on the lateral periphery of the circuit board in one side of the first slit, and a feed line placed on the first slit and adapted to feed the radiation portion from the other side of the first slit. The radiation portion further comprises a second slit extending from the first slit to the lateral periphery of the circuit board across part of the conductive layer forming the radiation portion, and a frequency adjustment element placed on the second slit.
